Hey guys,i wanne know if i can drop my belts in a bottle with some silecone spray.the reason is on outdoor tracks my belts getting really dirty with rubber and some times it also is on my diff.i wanne ask what i can do so that the rubber can find no grip to stuck on the diff and belts ..thanks

I use the silicone belt lubricant from BrilliantRC fantastic stuff and really makes a difference to the transmission and the belt never skips. We used to soak belts in WD40 years ago like the above poster.

I have used full synthetic motor oil to lube all belts since the HPI Micro RS4 days. A racer discovered that the lubrication greatly increased speed due to reducing the belt friction from rubbing on the chassis. But when I tried it I noticed that the pulleys NEVER EVER get clogged with junk when racing on carpet which was also a major problem on the car with our surface. Since then I've lubed every single touring car belt and have not needed to clean a pulley in well over a decade. Never had any issues with the belt skipping even at low tensions. Never had to replace a belt due to wear either.

Interesting.. I remember doing it all the time back in the micro days but never really gave it a thought when it came to Touring Cars. Might have to try that out.

A nice thing about full synthetic engine oil is that it's very tidy. It just vanishes or over time - no icky mess left behind. Nothing sticks. It's very different from all the typical lubricants and fluids we use on R/C cars.

Are you soaking the belt in the oil, how are you applying it to the belt?

What brand of synthetic oil are you using? I've seen sticky sythetic oil and the components are not going to evaporate so I'm curious about this.

About Brilliant RC Belt Silicon oil,
how often you lube the belt??? every race??

Everytime I rebuild the car I will clean the belts with an old tooth brush and then reapply the belt silicone and allow it to 'dry' then put the belt back in the car. When the belt is new I will apply the silicone a few times and allow it to soak right into the belt before putting it in the car...
